What custom fields are for
StockFlow tracks the fields most businesses need out of the box — SKU, quantity, cost, supplier, and so on. But every business has a few pieces of information that are specific to how they operate: a manufacturer part number, a hazardous-material handling note, a grant or funding source, a condition rating, a warranty end date. Custom fields let you add exactly those, without waiting for a built-in feature that fits your specific case.
A custom field is defined once (its name and type) and then shows up as an input on every product, so your team fills in a value per item rather than tracking that detail in a separate spreadsheet.
- Five field types: text, number, date, yes/no (boolean), and dropdown (select)
- Defined once, applied to every product in your catalog
- Reorder fields to control the order they appear on the product form
- Mark a field required so it can't be left blank when adding a product
- Deactivate a field you no longer need without deleting its historical data
The five field types
Text fields cover free-form notes — a handling instruction, a part number, a location description. Number fields work for anything numeric that isn't already a built-in column, like a weight or a rating. Date fields are useful for things like a warranty end date or a manufacturer date. Yes/no (boolean) fields work well for simple flags — hazardous, fragile, requires inspection. Dropdown (select) fields constrain input to a fixed list of options you define, which keeps data consistent across a team instead of everyone typing their own variation of the same value.
How many custom fields you can define
The number of custom field definitions you can create depends on your plan: 1 field on the free Starter plan, 20 on Professional, 50 on Business, and 999 (effectively unlimited) on Enterprise. This is a cap on how many distinct field definitions exist for your account, not on how many products can use them — once a field is defined, every product in your catalog can have a value in it.
